Well, now that I have released an updated version of GummyCharged for Froyo I have been asked multiple times whether or not I recommend one over the other.
I will do my best to give you list of what I know and believe...
Gingerbread for the Charge plus and negatives
+Extra bling - Screen off animation, Over-scroll glow
+Speed - The system feels very responsive even without the lagfix
+Netflix - You get Netflix compatibility
+Gtalk2 - With P3's hack you can enable the new Gtalk (although this causes other audio issues and I don't recommend it)
-Kernel - Without kernel source we have not been able to make custom kernels (I know one is in the works but we have yet to see that run stable)
-Light sensors - The light sensors in the GB kernel are broken resulting in no auto-brightness and no hard-key lights
-Games - While most games work some games still don't work for GB such as Dungen Hunter 2
-Signal - I noticed while using GB that I seemed to drop my 3g/4g signal for no apparent reason. this didn't happen often but when it did it was frustrating
-Quirkiness - Overall I think the stability of the leak is still someone quirky, I know this is just an opinion but its just what I have observed.
Froyo for the Charge plus and negatives
+Kernel - with the kernel source we are able to get custom kernels with both lagfix and voodoo sound
+Speed - With Lagfix enabled the overall speed of Froyo is still better than GB
+Stability - EE4 is rock solid stable
-Netflix - no Netflix

(ummm scratch that Netflix now works)
Really the look and feel across both GummyCharged GBE and FE are almost identical.. In fact you might have a hard time even noticing which one you are running.
